SSRS Expressions

Very practical expressions, when you create SSRS Reports in your day to day development.

1. Lets start with the easiest of the expressions i.e. To get Today’s date

=Today

2. Get Date +/- a number of days – The following code will get Today’s date -3 days. e.g. If today is the 08/12/2009, it should return 05/12/2009. You can change the -3 to any number and you should get the current date +/- the number specified. The DateAdd function basically adds an interval to a date. Here we add the interval -3 to Today’s date.

=DateAdd(“d”, -3, Today)

3. Get First Day of the Month – This is an extension of the pervious expression, it can be divided into two parts the -1.0 * DatePart(“D”, Today) + 1 returns the number of days from the first day of the month -1 in negative. i.e. If today is the 08/12/2009 it would return the value -7 which is then passed to the function DateAdd to get the first day of the month e.g. 01/12/2009

=DateAdd(“D”, -1.0 * DatePart(“D”, Today) + 1, Today)

4. Get Last Day of the Month – This is almost the same as the last expression, the only difference is we don’t add the +1 which gives us the last day of the last month then pass that date to another DateAdd function to add an extra month.

=DateAdd(“m”, 1, DateAdd(“d”, -1.0 * DatePart(“d”, Today), Today))

5. Get the First Day of the Last Month – This is another variation of the above expressions

=DateAdd(“D”, -1.0 * DatePart(“D”, Today) + 1, DateAdd(“m”, -1, Today))

6. Get the Name of the day – This gets the name for the day that was passed for example if its 08/12/2009 it would display “Tuesday”

=WeekdayName(DatePart(“w”, Today))

7. Check what day it is and display date accordingly (This checks to see if today is a Monday and if it is true then displays today -3 days else displays today -1 day)

=IIF(WeekdayName(DatePart(“w”, Today))=”Monday”,DateAdd(“d”, -3, Today),DateAdd(“d”, -1, Today))

8. Formatting Dates
Get Year – Will display only the year =Format(Today,”yyyy”) Years as 1900-9999
Get Month (without 0 suffix) =Format(Today,”M”) Months as 1-12
Get Month (with 0 suffix) =Format(Today,”MM”) Months as 01-12
Get Month by short Name =Format(Today,”MMM”) Months as Jan-Dec
Get Month by Name =Format(Today,”MMMM”) Months as January-December
Get Date (without 0 suffix) =Format(Today,”d”) Days as 1-31
Get Date (with 0 suffix) =Format(Today,”dd”) Days as 01-31
Get Date by short Name =Format(Today,”ddd”) Days as Sun-Sat
Get Date by Name =Format(Today,”dddd”) Days as Sunday-Saturday
Get Date in dd/mm/yyyy hh:mm:ss tt =Format(cdate(“01/31/2009 16:00:00″),”dd MM yyyy hh:mm:ss tt”) 31/01/2009 08:00:00 PM

9. Convert String to Date – Following example combines string and integer values to form a valid date format

=CDate( “1/” & Parameters!StartMonth.Value & “/” & Parameters!StartYear.Value)

10. SWITCH statement – An alternative to IIF/CASE (Returns a value depending on which condition is true)

=SWITCH(WeekdayName(Fields!Date.Value) = “Monday”,”Blue”,
WeekdayName(Fields!Date.Value) = “Tuesday”,”Green”,
WeekdayName(Fields!Date.Value) = “Wednesday”,”Red”)

11. Format Numbers as Currency – The result for the following will be $1000.00

=FormatCurrency(1000)

12. Convert integer values to string

= CStr(123123)
